Congratulations on your purchase of the Audio Note Meishu Line Integrated Amplifier. The Meishu is a Pure Class A Singled Ended valve amplifier that uses the highly regarded 300B direct heated triode valve. The Meishu produces a level of performance that is radically superior to current designs and was specifically designed for sonic performance rather than technical specifications. It also fulfills all Level 3 criteria.
-Pure Class A operation.
-Zero Negative Feedback.
-Single Ended Output Stage.
-Valve Rectification.
-Directly Heated Triode.
-Materials and component quality.
This Level 3 amplifier features Audio Note Silver wire and Audio Note signal capacitors.
UNPACKING AND INSTALLATION
The amplifier is shipped without the 3 large valves installed. It is necessary to install the valves first. It is essential that the valves are installed correctly or serious damage that is not covered by the warranty will result. We recommend that your dealer does this for you if you are unsure.
Please take the time now to fill out and send in your warranty card. This will serve as proof of purchase and ensure that all warranty work if ever needed is completed in a timely fashion.
Installing the valves
Please take care when unpacking the amplifier as it is very heavy and place on a suitable clean space (table or floor). We recommend that you store the packaging materials in case the unit requires shipping at a later date. Use a No.2 pozidrive® screwdriver to remove the top cover of the amplifier, 6 x screws for the top and 7 x screws for each side. Now remove the 3 valves that are packed inside the amplifier. Also inspect the inside of the amplifier to check that nothing has become damaged during transit including the remaining 9 smaller valves. Carefully unwrap the 3 valves. You will find 2 x 300B and 1 x 5U4G valve.
It is absolutely vital that these valves are fitted correctly.

Looking from the front of the amplifier install the 300B valves first. Inspect a 300B valve base and you will notice that two of the pins are larger than the other two. This is to help ensure that the valve can only be inserted one way.
(1) The larger pins must face each other when fitted to their valve bases on the central board.
(2) The sticker on the valve base must also line up with the sticker on the central circuit board., ie., A to A, B to B etc., or 1 to 1, 2 to 2 and so on.
(3) Also note the diagram on the output transformer also showing correct way of fitting. Please make sure that both (1), (2) and (3) are correct and with gentle but firm pressure insert the valve into its socket. Check again that all valves are fully inserted in the correct way to their respective valve sockets.
Looking from the front of the amplifier, the next valve to plug in is the 5U4G valve which goes into the last empty valve base on the right front board. Locate the rib or pip on the central pin on the bottom center of the valve and align with the valve base (the locating pin can only go in one way round due to a locating rib) and with gentle but firm pressure insert the valve.
Check again that all valves are correctly fitted and the top cover may now be replaced.
Installation
Select a suitable location for the unit ensuring that adequate ventilation clearance is provided allowing at least 30cm. of space above the unit. This is an important consideration as the amplifier generates substantial heat during normal operation. Be sure not to install the amplifier into a cabinet with restricted air flow or onto a thick pile carpet. In the interest of safe, reliable operation situate the amplifier away from dampness or direct sunlight. Site the unit on a flat and firm surface capable of sustaining the amplifiers weight. Worthwhile sonic improvements may be obtained by locating the amplifier on a purposely designed audio support system.
CONNECTIONS – Inputs
Line Inputs - Five line inputs are available for connection to CD, Tuner, Tape In, Aux
and AV. VCRs & DVDs may be connected to the AV input. Connect the Rec-Out sockets to the “Tape In” or “Line In” sockets of your Tape Recorder.
